Abstract

Un dispositif Venturi comprend un trajet d'écoulement primaire et un trajet d'écoulement secondaire introduit dans le trajet d'écoulement primaire, un écoulement d'un ou de plusieurs milieux fluides dans le trajet d'écoulement primaire et le trajet d'écoulement secondaire créant un tourbillon générant une aspiration au niveau d'une entrée du dispositif Venturi. Des systèmes incorporant le dispositif Venturi dans lesquels le trajet d'écoulement primaire est chargé avec de l'énergie sous la forme d'énergie thermique provenant de l'environnement ambiant par l'intermédiaire de la formation de vortex induite par écoulement. Des systèmes de compresseur de suralimentation incorporant le dispositif Venturi, le flux primaire d'air dans un moteur étant comprimé avec les gaz d'échappement recirculés à travers le trajet d'écoulement secondaire.
